RickRolling is a fake video link. Instead of getting the video you were looking for, you get Rick Astley’s “Never Going to Give You Up”. This started as a joke. It is considered funny because of the over-the-top dancing in this music video from the 80’s. Now, the video has gone viral (viral video: widespread popularity through the process of Internet sharing) and it’s all over the internet. If you’ve spent much time on youtube, you’ve probably been “rick rolled”.
